Abstract
A microcomputer including a flash memory and a CPU for carrying out verification of data written into the flash memory. A flash controller suspends the supply of a clock signal to the CPU when it receives a verification command from the CPU, establishes a verification condition, and reads data from the flash memory. After reading the data from the flash memory, it restarts the supply of the clock signal to the CPU so that the CPU receives the data. This makes it unnecessary for a program of the CPU for writing data into the flash memory to be transferred from the flash memory to a RAM, enabling the structure of the program to be simplified.
